In this page, you learn to wire the Battery Mixer that enables you to have mulitple batteries in parallel. 

Wiring 2 Infinite Battery on Generic controller

The wiring is quite strait forward using the given cables. The only difficulty is to make nice cable management so it's aesthetic. 

The way the mixer works:

• it enables you to hot swap batteries
• if batteries are not at the same level, the mixer will drain current from the highest battery.
• once at the same level, it will split the consumption between the two batteries

Wiring 1 Infinite Battery with a proprietary controller

Work in progress but in this case you should always have the proprietary battery connected so tit can speak with the controler.
